1 Claim, 2 Drawing Figures SAFETY DEVICE FOR HACKSAW SUMMARY OF THEINVENTION;

Myinvention is a safety shield device for mounting on a hand hacksaw.

The shield is formed of sheet metal, of 12 to 16 gauge, and shaped to beclamped onto a hacksaw frame at the handle end of the frame. The shieldcurves out and back around the knuckles and back of the hand graspingthe handle of the saw.

A major advantage of my invention is that it is adaptable for fitting onconventional hand-held hacksaws.

BRIEF DESCRIPTION OF THE DRAWING:

The objects and features of the invention may be understood withreference to the following detailed description of an illustrativeembodiment of the invention, taken together with the accompanyingdrawing in which:

FIG. 1 is a side view of the invention in use; and

FIG. 2 is a top view of the invention in use.

DESCRIPTION OF THE PREFERRED EMBODIMENT:

Turning now descriptively to the drawing, in which similar referencecharacters denote similar elements throughout the several views, FIGS.1-2 show a conventional hacksaw 11 with handle 13 and blade 14. Attachedto the blade frame 12 nearest to the handle 13 is a shaped metal shield15. This metal shield 15 acts as a safety device geared to protect thehand 18 of the user.

The shield 15 is formed of sheet metal of a size of 12 to 16 gauge whichis formed at the attachment end of the shield within a U-shaped bend 21,which fits about the hacksaw frame member 12. A bolt 17 is fastenedthrough the parallel sections of the U-shaped bend 21 for tighteningpurposes.

The shield 15 is formed in the sectional shape of an open curve so as tofit about the back of a users hand 18 that is grasping handle 13.

In use, the shield 15 guards the users hand 18 when, on the last strokeof the blade 14 cuts through the work being sawed.

Since obvious changes may be made in the specific embodiment of theinvention described herein, such modifications being within the spiritand scope of the invention claimed, it is indicated that all mattercontained herein is intended as illustrative and not as limiting inscope.

Having thus described the invention, what I claim as new and desired tosecure by Letters Patent of the United States is:

1. A sheet metal shield that may be readily clamped to the frame ofa-hacksaw for the purpose of protecting a hand of the user that isgrasping the handle of the hacksaw, said shield being shaped and fittedwith attachment means so as to locate the shield in a position that doesnot interfere with the replacement of a blade on the hacksaw,

said shield formed at one end in a U-shaped clamp 7 section of a size tofit about a frame member of the hacksaw that is generally orientedperpendicular to the axis of the hacksaw blade, with threaded fasteningmeans fitted to the said end of the shield for clamping the U-shapedclamp section about the same frame member,

said shield shaped in a curved form so as to rest, in the attached statein a location extending from the attached hacksaw frame member, to alocation about one side of the hacksaw handle and separated from thehacksaw handle by a space sufficient to permit positioning of the handof the user about the hacksaw handle and between the hacksaw handle andthe shield in said space.
